Stochastic Radio Channel Model for Advanced Indoor Mobile Communication Systems

A stochastic radio channel model (SRCM) for broadband indoor mobile systems operating at 5.2 and 17 GHz has been derived within the ACTS project AC085 Magic WAND. The SRCM was designed to accurately describe the time, frequency, direction, and polarization dispersive characteristic of real radio channels because these effects are important for the design of advanced receiver structures incorporating space diversity techniques or adaptive antennas. Such techniques are essential for Magic WAND and also for other future broadband mobile communication systems. The wideband SRCM takes into account all relevant propagation effects observed in real indoor environments. For example, it includes transitions describing emerging and vanishing propagation paths as well as the delay drifts of the multipath components when the mobile station travels through the coverage area of a cell. In the paper, the modeling approach adopted for the SRCM is briefly described together with a discussion on the main model features and a presentation of example simulation results.
